    Re: best servos for the job??

    Well.. I did alot of thinking so far and this is what i got as of now.

    Material list

    Skeleton: Plastic broom sticks (from a shop broom)/ weight- ?
    motors: rear power window motors/ weight- ?/ power- ?
    power: im thinking of a motorcycle battery, just to start with for now until i know the power draw from the motors

    Well this is the idea ( for now) lots will change down the road im sure. My dad runs a junkyard so i have lots of pickings to go through to get testing started. First things first i have to get my room done. Well what do you guys think??

    About 22Ah each. 45Ah is a reasonable number. So a motorcycle battery (at 12v? Better make it two) will hold up for a few minutes. Figure 6lbs each for the motors, another 30lbs in batteries. 4lbs for the controller. About 50lbs.

    You're going to build a 60+ lb walking robot from wiper motors and plastic broomsticks?

    Those wiper motors are going to rip plastic broomsticks to shreds...

    If your dad has a junkyard, you should be able to come up with something better than that

    Rear power window motors are pretty consistant. I've never seen one that doesn't draw between 20 and 30A.

    Whenever you power this thing up for the first time please have the video camera going. One way or another it is going to be spectacular.
